Abstract
Przedmiotem zgłoszenia jest sposób eradykacji drobnoustrojów z powierzchni płaskich, w tym skóry, odpowiedzialnych za infekcje skórne u zwierząt i ludzi oraz układ do realizacji sposobu, który charakteryzuje się tym, że stosuje się bezpośrednią ekspozycję powierzchni płaskich na zimną plazmę atmosferyczną (ang. Cold Atmospheric Pressure Plasma, CAPP), generowaną w formie wyładowań barierowych (ang. Dielectric Barrier Discharge, DBD) w formie strugi gazowej. Proces przeprowadza się stosując układ plazmowy z generatora prądu połączonego do: a) kwarcowej kapilary z elektrodami wolframowymi, b) wnęki z żywicy epoksydowej oraz c) wypełnienia wnęki wykonanego z krzemionki oraz izolatora. Do zwalczania chorobotwórczych drobnoustrojów stosuje się CAPP generowaną z użyciem helu jako gazu wyładowczego, który aplikowany jest do układu reakcyjno-wyładowczego z szybkością przepływu 2-10 L/min, a stosowana CAPP wytwarzana jest przy zastosowaniu prądu zmiennego o wartości wypełnienia 70% oraz częstotliwości modulującej 70%.The subject of the application is a method for the eradication of microorganisms from flat surfaces, including skin, responsible for skin infections in animals and humans, and a system for implementing the method, which is characterized by direct exposure of flat surfaces to cold atmospheric plasma (Cold Atmospheric Pressure). Plasma, CAPP), generated in the form of barrier discharges (Dielectric Barrier Discharge, DBD) in the form of a gas stream. The process is carried out using a plasma system with a power generator connected to: a) a quartz capillary with tungsten electrodes, b) an epoxy resin cavity and c) a cavity filling made of silica and an insulator. To combat pathogenic microorganisms, CAPP is used, generated using helium as a discharge gas, which is applied to the reaction-discharge system at a flow rate of 2-10 L/min, and the CAPP used is produced using alternating current with a duty cycle of 70% and a modulating frequency. 70%.
